Math Equation Animations

Touying also provides a unique and highly useful feature—math equation animations, allowing you to conveniently use pause and meanwhile within math equations.

Simple Animation​

Let's start with an example:

#slide[
  Touying equation with pause:

  $
    f(x) &= pause x^2 + 2x + 1  \
         &= pause (x + 1)^2  \
  $

  #meanwhile

  Touying equation is very simple.

We use the touying-equation function to incorporate pause and meanwhile within the text of math equations (in fact, you can also use #pause or #pause;).

As you would expect, the math equation is displayed step by step, making it suitable for presenters to demonstrate their math reasoning.

Complex Animation​

In fact, we can also use only, uncover, and alternatives:

#slide(repeat: 3, self => [
  #let (uncover, only, alternatives) = utils.methods(self)

  $
    f(x) &= pause x^2 + 2x + uncover("3-", 1)  \
         &= pause (x + 1)^2  \
  $
])
